5x^2+5y^2-20x+10y+21=0

Lösung

5 x^{2} + 5 y^{2} - 20 x + 10 y + 21 = 0

Lösung

(a, b) = (2, - 1), r = \frac{2}{5}

Schritte zur Lösung

5 x^{2} + 5 y^{2} - 20 x + 10 y + 21 = 0

Rewrite

5 x^{2} + 5 y^{2} - 20 x + 10 y + 21 = 0

in the form of the standard circle equation

(x - 2)^{2} + (y - (- 1))^{2} = (\frac{2}{5})^{2}

Therefore the circle properties are:

(a, b) = (2, - 1), r = \frac{2}{5}
